Luka Sulic quotes:

We tune differently, and we use some tricks. There's just the two of us for much of a concert, so we want a big sound. We do use some guitar effects, distortion and delay. Playing cello with distortion sounds so good.

Everybody recommends New Zealand. I really want to learn this haka, the traditional dance - I love it; it's so cool.

When our video of 'Smooth Criminal' came out, suddenly we started getting all kinds of offers. We were getting calls from TV shows like 'Ellen DeGeneres' and from record labels.

The cello is such a versatile instrument. It can rock like the hardest rock guitar, and it can sing like the human voice. We couldn't do what we do without the classical training. It's a hard instrument to play. There are no frets, and it takes finesse and technique to play.

Of course we had the best possible classical education, which gave us a very strong foundation and tradition. But we also learned a lot by collaborating with different pop/rock artists and especially by recording and working in the studio.

Because in classical music cello is not regarded as a popular choice, it's always playing the long, boring notes.

Don't wait for someone to call you up. You can do anything. You have all the possibilities in the world.

For us, it is all about breaking the boundaries between different genres of music and combining different styles of music and performing what we are passionate about. We are so lucky that we can experience both worlds: the more intimate classical world and the wild and crazy world of rock n' roll.

Even in classical music, the cello doesn't get a lot of respect because the piano and the violin get it all.

I like to swim a lot, while Stjepan likes to take long walks with girls. He's the very romantic type. Yes, musicians are romantic.

A cello can sound like so many instruments, but it's only one, you know, like a guitar; it has percussive qualities. It can sing like the violin, you know, like a voice.

Of course, there will always be, you know, conservative classical people who will judge you, but you know, who cares about them?

The range of the cello is so big, it can play as low as the double bass and as high as the violin. It has the perfect shape, and its sound is the closest to the human voice.

We want to connect all these musical worlds together. We just improvise; we know straight away if its going to work or not. They're not covers - I hate the word cover. We do a transcription: mix it up, put our own spin on it. I think people will be surprised how powerful our show is.
